MEDICINAL SPBAYING DEVICE.

Application filed March 9, 1926. Serial No. 93,487.

The object of this invention is to provide a spraying device for use in the treatment of the scalp, and for use in bathing.

A further object is to provide a device of special construction, in which salts, tor

the treatment of rheumatism, skin afiections and the like, may be 'inclosed in a container,

and the current of water, flowing from a faucet thru a flexible tube, may be carried directly thru the body of material to be dissolved by the water, and may be carried thence thru a nozzle, the container and nozzle both being flared outwardly or towards the discharge end.

With the foregoing and other objects in view, the invention consists in the novel construction and arrangement of elements described, illustrated and claimed, it being understood that modifications may be made parting from the spirit of the invention.

In the drawings forming part of this application, t

Figure 1 is a view of the device in end elevation, the flared end of the nozzle being shown.

Figure 2 is a view in longitudinal section.

Figure 3 shows the container for salts or the like, after its inner end has been moved slightly from the adjacent end wall so that liquid may flow to chamber 23. a

In Figure 2, a short length of flexible tub ing is designated 10, andthis element has connection with the smaller end 11 of the nozzle structure. A chamber 12 is provided adjacent to the portion 11. and" the walls 13 of the nozzle flare outwardly from the structure forming the chamber 12, and extend to the extreme outer end of the nozzle, being made thinner, if desired, at 15, and being moderately heavy towards the end, as shown at 16.

This portion 16 is internally threaded at 17, and the end of the nozzle may be slightly ornamental in form as shown in Figure 1, where the outwardly turned portions 18 provide a flanged structure.

Extending thru the portion 13 is a tapered bore 19 communicating with chamber 12 and with the passageway at 20, where the tube 10 has connection with portion 11. The container is preferably elongated and has a somewhat narrow entrance portion at 21, the

within the scope of the claims, without at:

walls flaring outwardly, so that a tapered structure 1S formed, whenthe element is con sidered from one point of view, although the term flared better suits the condition, since the current is flowing from left to right in Figure 2. An annular space 23 may be pro vided between the portions'15 and 22, but the outer portion of the container is of substantially the same diameter as the portion 16 of the nozzle, where the latter is threaded, as shown at 17.

The outer wall of the container may be of ornamental form, if desired, and in any event will be provided with a plurality of apertures 24, thru which the medicated fluid passes.

The flared portions of the nozzle and container, permit the water entering thru the reduced entrance portion, to spread thruout the body of material within the container,

thereby lessening the pressure, so that the water will have a period of time in which to become thoroughly impregnated with the material being dissolved, and there will be less tendency to force out the finer particles thru the opening 24 before they are dissolved. In view of the construction disclosed, the pressure may be still further modified by unscrewing the container slightly, providing an opening at the inner end thereof communicating with chamber 23. This also provides a type of cushion, reliev ing action similar to water hammer.

It will be observed that the longitudinal axes of the container and tubular portion or nozzle surrounding the container, are coincident.

. Having thus described the invention, what is claimed as new, is:

1..In a device of the class described, a flared nozzle and a flared container open at the inner end thereof and mounted in the nozzle, an annular chamber being provided between the container and nozzle, and the nozzle including a transverse wall with refer ence to which one endof the container is movable, providing an entrance to the annnlar chamber, the longitudinal axes of the nozzle and container being coincident, and said container having an apertured wall adjacent to the flared end of the nozzle.

2. In a device of the class described, a flarednozzle and a flared container mounted therein, the nozzle and container having enher and the container and nozzle having trance openings in alinement, centrally of threaded connection at their outer ends. said elements, an annular chamber being pro- In testimony whereof we aflix our signa- 10 vided between the container and nozzle, and tures.
